Those will appear in the syslogs for the reduce tasks. The tasktracker logs will just have the shuffle status messages (no exception traces, etc.). > TaskTracker falls into an infinite loop. > ---------------------------------------- > > Key: HADOOP-1374 > URL: https://issues.apache.org/jira/browse/HADOOP-1374 > Project: Hadoop > Issue Type: Bug > Components: mapred > Affects Versions: 0.12.3 > Reporter: Konstantin Shvachko > Assigned To: Arun C Murthy > Fix For: 0.13.0 > > > All maps had been completed successfully.
